Connecticut abolished operational county governments in 1960; New Haven County is a Census/judicial region only. The area is split between the South Central Regional Council of Governments (SCRCOG, 15 municipalities including New Haven, Meriden, Milford, Hamden, West Haven) and the Naugatuck Valley Council of Governments (NVCOG, 19 municipalities including Waterbury, Naugatuck, Cheshire, Wolcott). ADU regulation occurs at the town level under home rule, governed by Conn. Gen. Stat. Sec. 8-2 (zoning enabling act). Public Act 21-29 (HB 6107, 2021) requires municipalities zoning under Sec. 8-2 to allow ADUs as of right on lots with single-family homes unless the town has formally opted out by a two-thirds vote of the legislative body and the planning and zoning commission.

New Haven County has no operational county government (abolished 1960). Fireworks are regulated statewide under Conn. Gen. Stat. Sec. 29-356 and Sec. 29-357. Connecticut prohibits virtually all consumer fireworks. Only sparklers and fountains containing no more than 100 grams of pyrotechnic mixture per item, that are nonexplosive and nonaerial, are legal for persons 16 or older. Public displays require a permit from the local fire marshal under Sec. 29-357(c) and a state-certified pyrotechnic operator under Sec. 29-356a.

New Haven County has no operational county government (abolished 1960). Pool fencing is governed by the Connecticut State Building Code, which adopts the International Residential Code (IRC) Appendix G/AG105 (Barriers for Residential Swimming Pools). Barriers must be at least 48 inches high, with no openings allowing a 1-3/4 inch gap, and gates must be self-closing and self-latching opening outward. A pool alarm is required by Connecticut law before a residential pool building permit can be issued.

New Haven County has no operational government (abolished 1960). Dog control in Connecticut is governed by Conn. Gen. Stat. Sec. 22-364 (roaming-dog prohibition) and Sec. 22-363 (nuisance dogs), with each town employing a municipal animal control officer under Conn. Gen. Stat. Sec. 22-331. New Haven Code Sec. 7, Waterbury Code Chapter 6, Meriden Code Sec. 71-1 et seq., Milford Code Chapter 4, and Hamden Code Sec. 64-1 layer additional leash and licensing provisions on top of the state framework.

Connecticut abolished operational county government in 1960, so New Haven County itself has no noise ordinance. The region is served by the South Central Regional Council of Governments (SCRCOG, 15 towns including New Haven, Meriden, Milford, Hamden, West Haven) and the Naugatuck Valley Council of Governments (NVCOG, including Waterbury, Naugatuck, Cheshire, Wolcott). Towns regulate noise under home-rule authority in Conn. Gen. Stat. Sec. 7-148(c)(7)(A) plus the state framework in Conn. Gen. Stat. Sec. 22a-67 through 22a-76 and CT DEEP Regulations Sec. 22a-69-1 through 22a-69-7.10, which cap residential nighttime (10 p.m.-7 a.m.) noise at 45 dBA at the property line.

New Haven County has no operational government (abolished 1960), so fence height limits are set by each town under the state zoning enabling act, Conn. Gen. Stat. Sec. 8-2. Typical New Haven County rules cap fences at 4 feet in front yards and 6 feet in side and rear yards, with corner-lot sight-line setbacks. New Haven Zoning Ordinance Sec. 32, Waterbury Zoning Regs Sec. 4.05, Meriden Zoning Regs Sec. 213-39, Milford Zoning Regs Sec. 6.1.5, and Hamden Zoning Regs Sec. 600 each codify these standards. Conn. Gen. Stat. Sec. 47-43 governs civil 'spite fence' actions.

New Haven County has no operational county government (abolished 1960). The county fronts Long Island Sound from Milford east to Madison and is drained by the Quinnipiac, Housatonic, Naugatuck, and Mill Rivers, creating both coastal and inland flood exposure. Flood-zone regulation is governed by FEMA's National Flood Insurance Program, the Connecticut Coastal Management Act under Conn. Gen. Stat. Sec. 22a-90 through 22a-112, the Connecticut Inland Wetlands and Watercourses Act under Conn. Gen. Stat. Sec. 22a-36 through 22a-45, and the state Flood Management Act in Conn. Gen. Stat. Chapter 476a (Sec. 25-68b et seq.).
